You could try and copy and paste someone else’s Privacy Policy, rewrite it to fit your website and then paste it onto your website. However, by doing so, you’d be committing copyright infringement, which could get you sued. Also, you don’t know whether that policy is compliant with the current laws and it won’t auto-update for you, meaning that you’ll have to keep track of the changes to the law which are increasing.
Having us generate a policy for you is much easier, less time consuming and safer.
